Add DNS TXT records

We recommend that you add DNS TXT records to allow mobile devices to resolve the address of the CSA. This makes the enrollment process much easier for users. The following scenarios show the differences in the enrollment process with or without the TXT records.

3.When it fails, the device user is prompted to type in the URL to the CSA, including the name of the core. The agent connects to the CSA and enrolls the device.

Since the URL may be long and complicated (see below), the extra step may introduce errors and cause support calls. If you do not add the TXT record, you may consider taking other steps to prevent users from typing in a long URL on their devices when they enroll, such as using a URL shortener.
